I cant figure out this pattern
My pattern reads: skip 4 sc, (dc,ch1,dc,ch1,dc,ch,d1) in next st. My first question is which st to crochet in. My second question is if i should do all of those crochets in one st because when i look at the reference photo, it doesnt look right. I'm really eager to finish this project and i'm really worried my time and effort was a waste because i couldnt figure this out. Please reply soon, thanks.
